GM is 18436572 for V8's. Looking at the engine from the front the #1 is usually at about 5 oclock on the distributor on the VIN E motor. It's at the 12 oclock position on the VIN Y engine. The 8th position of the VIN determines the motor type.. Number 1 position is often marked on the distributor cap tower. Number 1 cyclinder is drivers side front.

On the back of the block the actual engine feel u will feel a bunch of numbers thats the fireing order first u can look on thev label around the raditator there should be 1 2 or even 3 stickeers saying what kind of ncar how many liters the fireing order and thats what u want

By mixing the plugwires up all you did was mess up the firing order. If you have the correct firing order, just plug the appropriate wire to the appropriate spark plug. You do not need to unhook the Battery. Unhooking the battery resets your computer and you do not need to do that for this problem.

Buy the appropriate spark plugs from your auto supply store. They will need to know your engine size (# of Cylinders Etc.) as well as the info you have supplied here (yr make model) Gap the new plugs to manufacturer specs. Follow the plugs wires from the distributor to the plugs. Remove plug wire and unscrew one plug at a time so you do not mix up the firing order and replace with the new plug. Put wire back on. You may want to replace the distributor cap and rotor at this time as well. Be sure, again not to mix up the order of the wires. Mark them in some way so you know how to put them back on the new cap in the same order they came off of the old cap. Medical tape and a numbering system works well. Also use a felt pen to mark the old and new caps to correspond to the numbers on the tape. Does this help? Let me know. Thanks.
